Resistance to microtubule-targeting agents such as taxanes and vinca alkaloids is often driven by drug efflux and changes in tubulin behavior. Targeting the colchicine-binding site provides an alternative strategy that may circumvent these resistance mechanisms.
RuvB-like 1 (RUVBL1) and its paralogue RuvB-like 2 (RUVBL2) are evolutionarily conserved members of the ATPases associated with diverse cellular activities (AAA) superfamily. In a recent study, researchers from Eikon Therapeutics Inc. aimed to leverage the protein dynamics of RUVBL1/2 to facilitate the development of novel inhibitors, instead of using ADP-based biochemical assays, to explore the therapeutic potential of this target.
Shanghai Henlius Biotech Inc.’s HLX-48 for injection has received approval from the Human Research Ethics Committee (HREC) in Australia and been acknowledged by the Therapeutic Goods Administration (TGA). The first-in-human phase I study in Australia will evaluate HLX-48 in patients with advanced or metastatic solid tumors.
Circular RNA (circRNA) is not a new concept, but it is a novel strategy in the field of gene and cell therapy. While mRNA vaccines have revolutionized medicine, this RNA fragment without free ends surpasses their performance in both efficacy and durability, bringing it to the attention of several pioneering companies. The latest advances in circRNA presented at the 29th Annual Meeting of the American Society of Gene and Cell Therapy (ASGCT) clearly surpass the performance achieved with linear mRNA.
Phrontline Biopharma (Hangzhou) Co. Ltd. has prepared and tested bispecific antibody-drug conjugates (bsADCs) comprising a bispecific antibody targeting B7 homolog 3 (B7-H3; CD276) and EGFR (HER1; erbB1) linked to a cytotoxic drug. They are described as potentially useful for the treatment of cancer.
Shanghai Allink Biotherapeutics Co. Ltd. has discovered new bispecific antibody-drug conjugates comprising a bispecific monoclonal antibody linked to a cytotoxic drug potentially useful for the treatment of cancer.
Foghorn Therapeutics Inc. has synthesized proteolysis targeting chimera (PROTAC) compounds comprising an E3 ubiquitin ligase-binding agent coupled to a histone acetyltransferase p300 (EP300)-targeting moiety. As such, they are described as EP300 degradation inducers potentially useful for the treatment of cancer.
Mesothelin (MSLN) is a highly expressed protein in several cancer types but with limited expression in normal tissues. Simcere Pharmaceutical Co. Ltd. has presented preclinical data on the characterization of SCR-A019, an antibody-drug conjugate (ADC) carrying a topoisomerase 1 inhibitor payload and an antibody that binds to membrane Mesothelin (MSLN) over soluble MSLN and has shown robust antitumor efficacy in several cell-derived xenograft models.
Pheast Therapeutics Inc. has presented preclinical data on PHST-677, a novel bispecific antibody-drug conjugate (ADC) targeting E-cadherin (CDH1) and Nectin-4.
